Nasal immunity against influenza

Immunity in the Nose to inFLUENza: Correlates of Efficacy (INFLUENCE)

['FUNDING_OTHER'] · IMPERIAL COLLEGE OF SCIENCE, TECHNOLOGY AND MEDICINE · NIH-11332178

This project uses gentle nasal sampling and stored flu-challenge samples to learn how immune responses in the nose could help protect people from influenza.

What this research studies

You may be asked to provide small, painless nasal secretions collected with a nasosorption device, which captures proteins and antibodies from the lining of the nose. Researchers will compare these new nasal samples from healthy volunteers with biobanked samples from people who underwent controlled influenza exposure. The team will develop and use tests that measure not just antibody levels but whether those mucosal antibodies can stop or clear the virus. Results aim to standardize nasal sampling methods and clarify which nasal immune responses matter most for preventing infection.

Who could benefit from this research

Good fit: Ideal participants are healthy adults willing to provide nasal samples or who have previously taken part in influenza challenge studies and donated samples to biobanks.

Not a fit: People with severe, ongoing influenza illness or unrelated chronic non-respiratory conditions are unlikely to benefit directly from this study.

Why it matters

Potential benefit: If successful, the work could help guide vaccines or treatments that strengthen nasal immunity to better prevent flu infections.

How similar studies have performed: Previous work shows nasosorption reliably collects nasal proteins, but measuring the functional activity of mucosal antibodies is a newer area with limited prior results.
